What was going to come of all this, she wondered?

What might happen if Sim were caught was too disheartening to think of, so Arden tried to piece together the events of the afternoon in a brave effort to keep awake.

The whole affair had so many missing links, though. It was just Sim’s usual good luck that she was not missed by Mrs. Malvern when the girls returned to school.

“Oh, dear!” sighed Arden at the thought of how she and Terry would have been put to it to explain. But they had not been obliged to do any explaining—so far.

The mouse, grown bolder in the silent darkness, was conducting a rustling, rattling search among some papers on a desk for tasty crumbs. Arden got up quietly and reached for another tennis ball. As she stood up she looked once more toward the highway and waited in strained tenseness.

Yes, she was sure of it. Far down the road a light bounced about as a speeding car neared the college.

“Terry! Terry!” Arden whispered. “I think they’re coming! Wake up!”

Terry was up in an instant and glided over to the window.

“It’s a car, sure enough. But we’d better make certain before we start down. Keep watch while I fasten the belt of my robe.”

“I will,” whispered Arden.
